Positively and negatively charged versions of the same particle have been entangled for the first time, allowing us to map the hearts of atoms more precisely and opening the doors to more powerful communication tools.

The neutrons and protons that make up the nuclei of atoms are, in turn, composed of quarks. However, quarks alone would be unstable; they need gluons, the carriers of the strong force, to hold them together. Gluons are orders of magnitude too small to see, even with the most powerful microscopes – but they can still interact with photons to produce exceptionally short-lived rho particles that decay to charged two-quark particles called pions.

By measuring the angles and speed at which the positive and negative pions (π⁺ and π^-) emerge, scientists at the Brookhaven National Laboratory have created a map of gluon distribution within the nuclei of gold and uranium atoms. They report this map to be the most precise description of the inner workings of an atomic nucleus.

Talk Overview: The human brain is extremely complex with much greater structural and functional diversity than other organs and this complexity is determined both by one’s experiences and one’s genes. In Part 1 of his talk, Lichtman explains how mapping the connections in the brain (the connectome) may lead to a better understanding of brain function. Together with his colleagues, Lichtman has developed tools to label individual cells in the nervous system with different colors producing beautiful and revealing maps of the neuronal connections.
Using transgenic mice with differently colored, fluorescently labeled proteins in each neuron (Brainbow mice), Lichtman and his colleagues were able to follow the formation and destruction of neuromuscular junctions during mouse development. This work is the focus of Part 2.
In Part 3, Lichtman asks whether some day it might be possible to map all of the neural connections in the brain. He describes the technical advances that have allowed him and his colleagues to begin this endeavor as well as the enormous challenges to deciphering the brain connectome.

IBM Research hosts a fascinating seminar with Rafael Yuste, a world leader in optical methods for brain research. According to Professor Yuste, lifting neuroscience studies from looking at neurons one at a time to ensembles or functional units is key in our quest to understanding how brains work.

Rafael Yuste is a Professor of Biological Sciences and Neuroscience at Columbia University and Co-director of the Kavli Foundations Institute for Neural Circuitry. He recently helped launch the BRAIN Initiative, a large-scale scientific project to systematically record and manipulate the activity of complete neural circuits.

AI researchers aim to achieve stability, speed, manipulability and a gain in operational height from for the robot by using machine learning and a 3D printed stick on the robot’s hind legs to allow quadruped transformers to become a humanoid biped robot and walk. Quantum researchers designed a machine learning-based method that shows how artificial controllers can discover non-intuitive pulse sequences that can rapidly cool a mechanical object from high to ultra cold temperatures, faster than other standard methods, which could be used to advance quantum computers. Researchers used deep reinforcement learning to arrange atoms into a lattice shape, which could be used to create new materials and nano devices, including a robot arm mate of atoms.

Black holes are areas of space-time where gravity rules supreme: A black hole’s gravitational pull is so strong that nothing, not even light, can escape. They range in size from stellar-mass black holes, whose masses can range from five to 100 times that of the Sun, to supermassive black holes, whose masses can exceed a billion solar masses. Astronomers now believe that supermassive black holes exist at the center of most galaxies. (A notable exception to this rule is M33, which appears to lack a central supermassive black hole despite being the third largest member of our Local Group.)

SpaceX Starlink Internet service will soon be available across the West African country of Nigeria, according to Nigeria’s Minister of Communications and Digital Economy Isa Ali Pantami. SpaceX already delivered some Starlink user terminals to the country to commence services. “As part of the partnership, SpaceX is to provide broadband access across the whole of Nigeria, enabling nationwide access to broadband connectivity way ahead of the December 2025 schedule, as outlined in our national broadband plan,” said Pantami. “With this collaboration with SpaceX’s Starlink, Nigeria is set to be the first African country to introduce the service.” Nigeria’s goals was to cover 90% of the country’s population with reliable internet access by 2025, the goal is now attainable because the Starlink satellite network is easy to set up and capable of beaming high-speed internet to rural and remote communities. SpaceX’s official Starlink Coverage Map says the service is ‘coming soon’ to Nigeria, users must input their address on the website to find out if its already available in their specific area.

The company sent an email to potential customers living in Nigeria, stating that the service is available for pre-order. “Order now to reserve your Starlink expects to expand service in your area [Nigeria] in 2023. You will receive a notification once your Starlink is ready to ship,” the email says. The hardware to access the satellite internet service costs $600 [N438,000] in Nigeria with an internet subscription of $43 [N31,390] per month.
